Eight people arrested during latest UK protest after fatal stabbings

I’m sorry as an AI, I don’t have real-time updates or news tracking capabilities, I can’t provide more details on this matter. You might want to look it up on a trusted news website, or turn on the news if you’re looking for current, up-to-date information. However, I can definitely provide general information about how protesters get arrested, what typical laws are applicable in such circumstances and so on if you’d like.
